Hello @all,
Dates in org-format in heading break the beamer export:
Minimal case:
#+OPTIONS: H:3
* title [2013-09-29 Sun]
** section
*** frame
text
Result for beamer export:
org-latex-compile: PDF file ./beamer-bug-date.pdf wasn't produced: [undefined control sequence] Runaway argument
The same error for:
#+OPTIONS: H:3
* title <2013-09-29 Sun>
** section
*** frame
text
This works:
#+OPTIONS: H:3
* title (2013-09-29 Sun)
** section
*** frame
text
The export in latex for the same snippets works in all cases in version:
Org-mode version 8.2 (release_8.2-6-gd08917 ...)
Regards,
Daniele

It's a LaTeX Beamer problem: it doesn't like
\section{title \textit{[2013-09-29 Sun]}}
produced by Org, although regular LaTeX accepts it.
Do you know about a workaround for this?

This is really a workaround: put a \protect before \textit.
In general, putting formatting commands in \section title etc., even if
not erroneous, is considered a bad practice.

Not really.

Or why not drop \textit?

But org-mode allow this!
I think that if something is allowed in org-mode syntax but not by the
underlining tools used for export, the exporter should take care to find
a suitable workaround.
I just found that the same problem (work in latex, does not work in
beamer) exists for footnotes in header!
A feature request would be to have some checks on org files a la
flymake, at least for common potential sources of problems that
usually break the export like:
- missing two empty lines after footnotes
- missing empty line after RESULTS:
- =string=[footnote]
Maybe something already exists and I am simply not aware.

Daniele

Sounds good for me. (NB: there's a similar problems with tags, AFAIR.
And (AFAIR!) it's even worse, since the exporter uses a low-level TeX
command \hfill.)

Definitely agreed. The point is, what is a "suitable workaround"?
One idea is to define a command \orgsection, with syntax like this:
\orgsection[timestamp=...,tags={...,...}]{title proper}
This could be even defined in a specialized package, call it org.sty,
which is then turned on by means of \usepackage in exported files.
This is probably the cleanest solution I can think of, but has one
disadvantage: it diverges from LaTeX syntax, so if I edit manually (or
worse, transform automatically) such a file, I can encounter problems:
the (non-TeX) parser (e.g. an editor's one) may not know that
\orgsection is in fact a flavor of \section. For pdf export this is a
non-issue, but AFAIK people use Org LaTeX export to create a file for
further work on it.
Another idea is to redefine \section so that it either accepts optional
arguments (therefore breaking its default interface!), or allow
something like this:
\timestamp{...}
\tags{...,...}
\section{title proper}
This is easy to do, but far from elegant. Also, it does not help
further maintenance of such a LaTeX file.
Yet another solution would be to forget about LaTeX and use ConTeXt,
where defining custom sections etc. is much easier. Of course, this is
fine only assuming that (1) I do not want to e.g. submit my file to a
LaTeX-accepting journal and (2) I'm fine with learning ConTeXt, which -
even though much better than LaTeX in terms of UI (and also
featurewise, btw) - has its own learning curve.

Quite possible. You can always use \footnotemark and \footnotetext.
(Beamer hacks deeply into LaTeX innards, so things like this are no
surprise.)

I think this is rather ambitious and would make life very difficult for
exporter maintainers. LaTeX, for instance, is a very complex system.

Well, there is `org-latex-active-timestamp-format',
`org-latex-inactive-timestamp-format' and even filters can do it.
It is also technically possible to write in ox-latex a section-local
specific export back-end that would translate differently some objects
in a \section{...} command. But that would make the export a bit more
unpredictable.
Of course, in a few cases, `latex' back-end does its best to circumvent
possible problems (i.e. nested footnotes), but this is nowhere near
a general rule. It's usually a lot of work for a tiny corner case.

I disagree. This is just unrealistic. There are many packages involving
many quirks. We cannot afford to provide a workaround to all (or even
most) of them, assuming one exists.
Also, the OP is making a false assumption. The underlining tool allows
\texit in the section \command, i.e., you can type it in a "tex" file.
You will get a compilation error, exactly as if you do the same mistake
in Org. Why Org should be smarter in this case?

Maybe, I was talking about the default. (And I even don't know now how
to correct it, since LaTeX does not have a notion of a "section tag" -
so there's no obvious way to represent such an entity in it!)

Sorry, I did not get that idea. We are not talking about
converting /different/ objects into /sections/, are we?

Well, in this particular case I can definitely live with what Org
gives. (The fact that I don't use the exporter too often helps;).)
In other words: the status quo *is* (more or less) a "suitable
workaround", at least for me.

Hm, I did not understand this point:(.
My opinion (as a LaTeX user and hacker, if I may say so) is that LaTeX
exporter may be not optimal, but it is decent enough. I agree that
it is a lot of work to make it better, and even then it's not enough,
since there is no "canonical" way to transform some Org-specific things
(like tags) to LaTeX syntax - so someone will be unhappy anyway...
What is important here (as I hinted previously) is the point of having
a LaTeX exporter: do we aim at pdf, not caring about the readability
and elegance of the (then intermediate) LaTeX file, or do we aim at a
good quality LaTeX file to do further (manual!) work on it, including
(but not limited to) "visual tuning". I'm sure there are some people in
both camps, and satisfying all of them may be tricky.
Now that I think of it, writing a completely new LaTeX exporter might
actually be a lot of fun - I'm afraid, though, that I don't have enough
time for it now...

Hello all,
I see all your interesting points on the discussion... I just want to
explain that my statement is my naïve interpretation of:
You can use intuitive markup then have it converted to HTML, LATEX,
ODT – and much more[fn:1].
I can understand that the markup can end in very complex cases, but I
hope that you agree with me that with this advertised feature an extra
care should be put in ensuring that every markup can be exported
without crashing some tool in the chain.
The latex and html exporters (the one I use most) do already a
wonderful job, but some important case are missing.
Since I found a healthy and friendly community I was thinking that was
worth reporting them.
In fact I use org-mode primarily to stay away from *tex
nuisances... and I think that I am not the only one. I know enough
latex to find a workaround myself (not enough to offer a general
reliable solution) but I do not think that this will be a pleasant
experience for a newcomer or to somebody that choose org-mode for the
latex export capability.
Regards,
Daniele

Hello Marcin,
This line do no really cause errors on latex but do no export the code
and/or the footnote and leaves the equals in the output. Here are
some cases:
#+OPTIONS: H:3
* title

*** subsection
test[fn:1] good: text, footnote, no equals
=test=[fn:2] bad: no code(bad), footnote, equals(bad)
=test[fn:3]= bad: code, no footnote(bad), equals(bad)
=test=\[fn:4] bad: code, footnote, no equals, slash(bad?)
=test=[fn:5] bad: no code(bad), footnote, equals (bad) (please note
that there is a zero with whitespace before “[”)
[fn:1] t1
[fn:2] t2
[fn:3] t3
[fn:4] t4
[fn:5] t5
* title 2

Fair enough. What, exactly, do you suggest as generated LaTeX code?
IIUC, you want to drop any markup for timestamps when located in
a headline, ignoring `org-latex-active-timestamp-format' and al. Am
I missing something else?
BTW, the =verbatim=[fn:1] case is unrelated to export. See
`org-emphasis-regexp-components'.

Yes, I think is fair to drop the markup. I would also think that this
is safe default when nested markup is bad.
Maybe the exporter can emit a notice/warning.

Yes, sorry, I mixed two not-so-related problem. The beamer exporter do not
work with this code:
#+OPTIONS: H:3
* title test[fn:1]
** section
*** subsection
[fn:1] text
The output is:
org-latex-compile: PDF file ./beamer-bug-footnote.pdf wasn't produced: [undefined control sequence] Runaway argument
The =verbatim=[fn:1] problem was discovered trying to find a
workaround for the footnotes in the headers...
Oh, in fact searching emphasis + footnote lead to some results.
The question hit this list periodically... so maybe it’s worth
documenting it better. I will try found a general answer and
propose a patch for the docs.
It seems that I am going to drop latex nuisances to go into elisp
ones ;-)
Thanks again,
Daniele

Do you have an exhaustive list of such cases?

That it dropped the markup?

Of course, that's a similar problem: footnotes are not allowed in
headlines. Though, in this case, it isn't possible to drop the markup.
What LaTeX code do you suggest?

No, not really but I try to report them as soon I found them. I do
want to replace latex entirely with org, so I will use it extensively
in the near future.

Yes, I do not know if there is already a standard in reporting back
but I would go for something like "Latex-exporter: Warning: dropped
code markup at line XX of originalorgfile.org because it is not
supported by this exporter. More info at ..." or even a shorter one
can be fine to me.

Mmm, I think you are asking to the wrong person. I do not know enough
about latex and its error reporting capabilities...
I would appreciate if the exporter does not break and/or a
notification to the user of the problem in and understandable
language, even for newcomers.
I know when latex do not know how to resolve some references put some
question marks... but I do not really know if this is the case to
follow this convention.
Regards,
Daniele

Well, LaTeX's error reporting capabilities are not very impressive...

Well, this is something different: it basically means that either (a)
you need another run or (b) you messed up with the references.

The following patch should protect some fragile commands in
a section-like structure. It is Beamer-only since general LaTeX back-end
doesn't seem to encounter these problems.
Does it fix the problem?

Hello Nicolas,
yes, the problem is fixed both for dates and footnotes in sections, and
should be fixed for any of: bold footnote-reference italic strike-through
timestamp underline if I understand it correctly. Nice! I hope you plan
to merge it.
Thanks you,
Daniele
